低摩擦床面における歩行開始1歩目の動作コントロールについて

movement control

The purpose of this study was to clarify how movement is controlled at the first step by the swing leg of gait initiation on a low friction floor. Nine healthy subjects (age: 22.6 ± 3.0 years) participated in the study. On both high and low friction floors, movements of the first step were measured using a force plate and a motion analysis system. The length of the first step and the time difference from heel contact to toe contact by the swing leg on the low friction floor were significantly smaller than those on the high friction floor, and the maximum vertical distance between the lateral malleolus of the swing leg and the floor on the low friction floor was significantly higher than that on the high friction floor. These findings suggest that the movement of the first step of gait initiation on a low friction floor may be controlled in such a way that the step length is reduced, the foot is raised higher, and the foot lands flat on its sole.
